My device is a Nexus 5x.
I am running the Bluetooth module and the control set is connected also.

When the ALP apk runs on Bluetooth I cannot get audio to playback in other apks. Music Player, UTube Videos, nothing will play back audio but for the ALP apk.
So I kill the ALP apk and it does not reverse. I have to reboot the phone.
The Bluetooth icon looks different when ALP is running.

Thanks
